Which non-metallic material is sometimes used to construct vessels for corrosive services?

• A. FRP (Fiber Reinforced Plastic)
• B. Polyethylene
• C. PVC
• D. Concrete

Answer: (A)

Fiber Reinforced Plastic (FRP) is an excellent choice for constructing vessels that deal with corrosive services due to its desirable characteristics. This material combines a polymer matrix with a reinforcing agent, typically fiberglass, which enhances the modulus of elasticity, strength, and thermal stability while maintaining a lower weight compared to metals. In corrosive environments, such as those involving chemicals or harsh conditions, FRP displays exceptional resistance to both corrosion and chemical attack, making it ideal for applications in the chemical processing industry, wastewater treatment, and storage of aggressive substances. This material also provides ease of fabrication and installation, which further contributes to its popularity in the design of pressure vessels for corrosive service.
